When thedamping arrangement isofthe magnetic retarded disc type,;the position of the damping magnets may readily be varied to {obtain any desired retarding efl'ect, to adjust the usual spiral al and error which requires a large stock of spri time, by persons skilled in the adjustment of such regulators, tonysecurethe proper setting.
